IMPROVEMENT IN BLOWER-TUBES FOR FURNACES.

Specification forming part of Letters Patent No. 117,206, dated July 18, 1871.

To all whom it may concern.-

Beit known that I, BAKER W. REYNOLDS, of Evansville, in the county of Vanderburg and State of Indiana, have invented a new and useful Improvement in Blower-Tubes for Boiler-Furnaces; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being' had to the accompanying drawing' forming a part of this specification.

My invention consists in applying a jacket to the blower-tubes for boiler-furnaces, as hereinafter fully described and subsequently pointed out in the claim.

Figure 1 is a longitudinal, and Fig. 3 a crosssection of a blower-tube with my jacket applied thereto. Fig. 2 is a view of the spacing-ring which keeps the two tubes apart.

A is the ordinary blower-tube, which is inserted Within the furnace, and C is a stout metal jacket, correspondingly shaped, but on a larger scale. Each of these tubes curves inwardly toward the point to produce the nozzles E E, While the jacket is perforated at K to prevent one or both from bursting under the expansion of the superheated steam in the space between the tubes. The condensed steam in the jet-tube A trickles over in the form of water upon the tube C, is reconverted into steam, and passes out at these apertures K. D is a cap, having two unequal recesses, into which are respectively screwed the blower-tube A and the jacketI (l. This cap also is provided with a threaded shank, B, by which the whole device may be attached to a steam-pipe.

By this jacket, thus constructed and thus attached to the pipe, the fire does not come into actual contact with the blower-tube, whereby the said tube is protected and prevented from being rapidly burned out.

Having thus described all that is necessary to a full understanding of Iny invention, what I esteem to be new, and desire to protect by Letters Patent, is-

In combination with an ordinary blower-tube, A E, for locomotive-boilers, the jacket C H, both constructed and arranged Within cap I), as and for the purpose specified.
